Screenshot metadata in academic research
Screenshots show up everywhere in academic work: a capture of survey software mid-run, a figure pulled from a lab tool, a screen grab included as supplementary material in a paper or thesis. They feel like plain images. But like any photo or screen capture, they can carry hidden metadata that has nothing to do with the research itself.
What rides along in a research screenshot
Depending on the device and software that produced it, a screenshot can embed a timestamp, device model, and the username or account tied to the capture tool. Some survey platforms, lab instruments, and annotation apps write their own fields into the image — software version, internal session IDs, sometimes an institutional login name. None of it appears in the picture, but it travels inside the file when you drop it into a manuscript, upload it to a journal's submission portal, or share it with collaborators and reviewers.
For most results this is a minor annoyance. But double-blind review depends on reviewers not being able to identify authors, and a screenshot carrying a university login or a named device can undercut that anonymity. Shared drives, preprint servers, and outside reviewers also see far more of your files than you might assume.
Why it's easy to overlook
A screenshot reads as "just an image of my screen," so it doesn't get the same scrutiny as, say, a dataset with personal information in it. But PNG and JPEG screenshots use the same file formats as any photo, and they can carry the same hidden fields. Pasting the image into a Word document or a LaTeX figure doesn't strip anything — the underlying image file, metadata and all, typically rides along into the final PDF.
If your submission also bundles a Word or PDF document — a cover letter, a data appendix, a supplementary methods file — know that scrub currently only detects hidden content in those formats; it flags what it finds but doesn't remove it yet. Review and re-export those manually. scrub's cleaning today covers image files like your screenshots.
Clean the screenshot before you submit
This takes seconds and never requires uploading the file anywhere:
- Take or export the screenshotAs usual, staying on your own device.
- Open it in scrubIt shows exactly what metadata the file is carrying before it goes into a manuscript or submission.
- Click Clean, then use itYou get a lossless copy with the hidden fields stripped — the image looks identical, the extra data is gone.
Everything happens locally. The screenshot never leaves your machine just to get checked or cleaned.
The short version
A research screenshot can carry device, timestamp, and account-adjacent metadata that has nothing to do with your findings — and can even work against anonymous review. Strip it locally before it goes into a paper, thesis, or submission portal. Get scrub free and clean a screenshot in seconds.
